Experience summary

Professional Project Experience:-

1. Correlation of Frontal impact occupant crash protection analysis:

In this project, we simulated full frontal impact analysis as per

regulation.

. We monitored Vehicle Rear Sill pulse, scrutinized crushing of front

structure to absorb kinetic energy, Firewall intrusions on both driver

& passenger side.

. We focus on the progressive crush of crush zones, sequential stack up

of the vehicle front component, floor and center tunnel deformations

. Based on the analysis results, design enablers suggestions are given

to improve the Front structure energy absorbing capabilities, Engine

travel study, Steering wheel Displacement & load transferring

capabilities.

. Numerous iterations have been carried out to tune front compartment

crush modes.

. After Physical test, Rails and Other front components Crush behavior

are incorporated in virtual analysis model.

. Material testing is done for the few front end components and those

details are built-in to the vehicle model along with the Forming

effects for important load path components.

2. Offset frontal impact Occupant crash protection analysis:

In this project, we simulated offset frontal impact analysis on ODB

barrier.

. Analysis executed as per the IIHS regulation.

. We monitored Vehicle Rear Sill pulse, scrutinized crushing of front

structure to absorb kinetic energy; Firewall intrusions on both driver

& passenger side, wheel interaction with the Front sill section.

Section force and energy absorbed by the load path components.

. Based on the analysis results, design enablers suggestions are given

to improve the Front structure energy absorbing capabilities, Engine

travel study and few components are designed to fail at the particular

load to avoid energy being transmitted to passenger compartment.

. Numerous iterations have been carried out to tune front compartment

crush modes.

In this project, we monitored the following:

. Intrusions are plotted using standard template.

. Monitored Dash intrusion, Left Toe pan, brake pedal, steering

column,IP and waist level reduction

. Vehicle Rear Sill pulse

. Sill deformation, Sub-frame, Swan neck (rail to dash connecting

region) deformation.

3. 25% Offset frontal impact Occupant crash protection analysis: (Small

overlap)

In this project, we simulated 25% offset frontal impact analysis on Rigid

barrier.

. Analysis executed as per the IIHS regulation.

. We monitored Firewall intrusions on driver side, wheel interaction

with the Front sill section. Shot gun deformation, Section force,

Vehicle Rear Sill pulse, and energy absorbed by the load path

components.

. Based on the analysis results, design enablers suggestions are given

to improve the Front structure energy absorbing capabilities, few

components are designed to fail at the particular load to avoid energy

being transmitted to passenger compartment.

crush modes.

5. Seat belt anchorage strength analysis:

In this project, we simulated seat belt anchorages strength analysis for

driver, co-driver and rear passenger seats as per safety regulation. Loads

are applied at the anchorage location by using lap & torso loading devices

via seat belt as specified in the regulation and checked for the plastic

strain failure at the anchorage location, anchorage reinforcements and

other panels.

Only BIW and with closures considered for the

simulation and the BIW is constrained at long member as in physical test

for loading the structure.

In this project, we monitored the following:

. Front SBA: Plastic strains values are check against the

allowable percentage of elongation of material for Inboard and

Outboard anchorage locations, B-pillar Upper anchorage location,

seat mounting to the floor.

. Rear SBA: Same process of plastic strain values checked at the

anchorage location.

6. Side door intrusion analysis:

In this project, we simulated front and rear under-run protection device

analysis for heavy commercial vehicle as per AIS 69 and IS14812 crash

safety regulation. This device used in commercial vehicle to prevent small

vehicles such as cars from under-running below it. FUPD and RUPD devices

have to withstand the regulation specified load. Loads are applied on the

device at different points and the resistances offered by the device are

measured in the simulation.

Only vehicle long member and FUPD or RUPD device considered for the

simulation and the long member is constrained as in physical test for

loading the structure.
